| 摘 要： | 为提高被加固混凝土梁的抗剪承载力,提出在梁底粘贴预应力碳纤维布和在梁端部两侧粘贴碳纤维布复合加固技术。设计了5根无腹筋混凝土梁,进行静力加载试验,试验分析不同加固方式对混凝土梁的抗剪承载力影响,同时对复合加固混凝土梁的斜截面承载力进行理论分析和推导,建立了实用的理论计算公式,理论计算结果与试验数据符合较好。

| Abstract: | In order to improve the shear capacity of a concrete beam,a new composite reinforcement technique is put forward through pasting CFRP on both sides of the end of the concrete beam and prestressed CFRP at the bottom.In this paper,five concrete beams without web reinforcement are designed to carry out the static loading experiment.Through this experiment,the impact of concrete beams on the shear strength in different reinforcement is analyzed,the oblique cross-section's bearing capacity of the composite reinf... |
